Hi Africa-listers,<div><br></div><div>
I want to set an informal assignment for my candidates, to help them
recognise common CRSes used in South Africa (South, not Southern).</div><div>
</div><div>
Off the top of my head I can think of:</div>
<ul>
<li>Non projected Lat Long</li>
<li>Lo system (North and/or South facing) projected from either
Clarke 1880 [if very old] or WGS84</li>
<li>UTM33-36S</li>
</ul>
Are there any others<u> in common</u> use?<div><br></div><div>
If so, by whom?</div><div>
</div><div>
Thanks and keep well,</div><div>
Zoltan</div><div>
</div>
